NASA Spacecraft Discovers New Magnetic Process in Turbulent Space
Вставка
- Опубліковано 7 сер 2024
- Though close to home, the space immediately around Earth is full of hidden secrets and invisible processes. In a new discovery reported in the journal Nature, scientists working with NASA’s Magnetospheric Multiscale spacecraft - MMS - have uncovered a new type of magnetic event in our near-Earth environment by using an innovative technique to squeeze extra information out of the data.
Magnetic reconnection is one of the most important processes in the space - filled with charged particles known as plasma - around Earth. This fundamental process dissipates magnetic energy and propels charged particles, both of which contribute to a dynamic space weather system that scientists want to better understand, and even someday predict, as we do terrestrial weather. Reconnection occurs when crossed magnetic field lines snap, explosively flinging away nearby particles at high speeds. The new discovery found reconnection where it has never been seen before - in turbulent plasma.

That makes sense due to the chaotic fluid of charged particles. These charged particles are clearly moving, which means they generate a magnetic field. Now you have a large mass/ quantities of these moving at fast (relative) speeds. Pretty cool stuff.
It is difficult to teach so well in such a short time. They've released a video that isn't an insult to our intelligence.
Except it is that exactly
But could they do the same with an American accent?
My god, these computer graphics are awesome!
victorarnault I know right
Magnetism has always been magical for me, I wish we knew what it really was?
Just incredible how there is so much yet to be discovered
dante i find it incredible that you chose to edit your comment in brief related to the genius of the content. that stated, i agree that 'thats not incredible. whats incredible is xyz' reactions do not often allow the leeway latitude or logistical leverage to be considered credible.
Very interesting, can you upload the audio on sound cloud, 144p is too much for my internet. My next question is how do fluxuations in the magnetic field affect our climate (specifically global temperatures). I really want to study that sometime
Astral Traveler suscribed.
Does these kinds of magnetic reconnections have anything to do with the heliospheric current sheet/IMF and how it interacts with the Earth's magnetic field? I'm looking into what creates the auroras and know the direction of the IMF has a huge influence on the auroras.
Can Magnetosheath be mirror reflection 1:1 of a Sunsheath if there is one?
Nice visuals, but fails on the audiosonics. Couldn't they turn the background noise down a bit so the diction might be better heard.
So, hypothetically, we could utilize these magnetic particles in space travel, right?
Yes
I agreee. Faraday. Maxwell, support it.
Hence electro-magnetic universe. No dark matter but rather Aether in space causing resistance
Got this research very useful in aerospace study.
Спасибо.
Beautiful.
It would be interesting to see what is the relation or the reaction between magnetic waves created by the sun or all the suns and the gravitational waves that flow in the cosmos if any. Just curious.
1:11 What's supersonic speed in outer space?
The only thing more impressive than cramming so much complex explanation into a short yet understandable video, is the science behind the discovery.
Does magnetic reconnection generate an opposing force?
I had no idea about the phenomenon of magnetic reconnection at all before this video. Pretty awesome stuff.
It _is_ awesome stuff! Though this “snapping rubber band” analogy is a bit exaggerated. At the basic level, reconnection is just a result of plasma having a non-perfect conductivity - only the idealised picture of perfect conductivity (ideal MHD) leads us to consider magnetic field-lines as physically stable objects in the first place, in reality they are only good as a local approximation. Reconnection is the dissolving of the magnetic topology, or, rubber bands slipping through your fingers as it were. Still causes some significant heating etc. though.
Very cool
they should use it to propell a spaceship fast through space
create a manetic repulsor engine
Right now im searching the internet for anything like this.
It just crossed my mind that if magnets have energy on their own, we could use that energy to travel fast in space.
This would be really cool to do!
Potential source for the "oh my god particle"?
That is similar to the "Cluster"-mission from 1996?
Could it be going faster because you flew something metal through it?
Absolutely incredible.
Indeed
At 1:10 you say that particles are "flung at supersonic speeds". Is the reference to sound velocity adequate for phenomena occurring in the empty space ? What is an order of magnitude of such a velocity ?
Perhaps it is a double layer?
I thought these reconnection events required a physical medium for the fields to follow. Are there enough of these particles to form continuous bands?
I thought I was understanding how this worked on the sun but the sun has lots of physical material to use as bands.
I'm not really expecting an answer, just voicing some of my frustration of trying to figure out how all this works.
Thanks for the interesting video NASA Goddard.
Naturally adds a shield layer deflecting rays.
I’m psyched
You can make electric power from these earth sun electrical interactions long length conductors take in this energy as geomagnetic currents
I would like to see the magnetic reconstruction video a screensaver. Question for you NASA, I've seen a lot of papers lately saying that Mars's magnetic field is very weak and thus the planet is extremely radioactive and probably a bad target for colonization. Does Venus have a stronger magnetic field and is it less Radioactive? If Europa is really the best decision to colonize what kind of rover would you plan to scope that planet out? Are you worried about radioactive octopus on the planet from that sci-fi movie? (Joke)
Dave Awesome Check out the europa mission proposal. Search 'Europa heat probe' and I am sure a video shows up. Don't know their current ideas but they wanted to send an autonomous rover contained in a heated probe which would melt itself into the Icy layer of Europa and release the autononous vehicle once it hits the subsurface ocean.
Venus's magnetic field is much weaker than the Earths. It provides basically no protection from solar wind particles.
Will Pack I haven't used winamp in years!! I loved it though.
The guy from Goddard who did some of this visualization was interviewed by Fraser Cain this same day. The Universe Today site (Fraser's) will have the link to the UA-cam video as I don't remember which of the several channels he has that it was on.
Dave Awesome: Mars' magnetosphere is practically nonexistent, its core having effectively shut down within its first billion years -- this being a consequence of its being so less-massive a planetary body than Earth (it's hypothesized that Jupiter's to blame for the diminutive stature of Mars, that Jupiter's enormous gravitational influence robbed Mars of rocky planetary building materials during and after the accretion period of the early solar syste). Once Mars lost its magnetosphere, it then over millennia of time lost its hydrosphere (oceans) and, due to its weak gravity, its atmosphere which vented into space and left it with incredibly thin atmosphere that it has now in the present-day. This adds another daunting challenge to the wild idea of terraforming Mars in that anything done to Mars' atmosphere to make it eventually breathable will be undone by its weak gravity being unable to hold it in place in perpetuity -- unless we can figure out how to jump-start its magnetosphere.
Magnetic reconnection.
Impulse force needed for deep space exploration?
YESSSS ! Double yes !
Amazing 👍
1:30 it's a roach!
And use those particles to generate energy
Brilliant
We need more about these events of flux transfer events.
Mind blown
same happening through naked eye on gas giants ..you see the effect with gas, and particule charge you can hear it through mic to what gas giant sound like
is this energy useable by spacecraft?
How about Pluto?
the last plasma apocalypse ripped this place up real bad like world splitting, are we ready for the next,
1:10 "as a result, particles in the region are flung at supersonic speeds"
Why are we measuring stuff in terms of sound when we're talking about electromagnetic radiation?? I mean I guess it's technically right, but that just seems a little like measuring a marathon in millimetres. I'm probably just missing something
Uhh... supersonic?! Through what medium?
Excellent presentation of these new findings.
WOULD BE GREAT IF RECORDING VOLUME WAS 5 TIMES HIGHER.
But there really isn't any lines, they are just like topographical contour lines on a map, they are just for image sake to give incremental information like elevation. There isn't really any lines connecting or reconnecting, that is just someones imagination.
Of course there are no lines in space. What's your point?
is this turbulent plasma what scientists of yesteryear would have called either?
That last bit of animation (zooming out from "solar system") doesn't belong on science channel.
I'm sure it was called "recombination" rather than "reconnection" when I learned about this.
mandela effect lol
ผู้เชี่ยวชาญครับผมสงสัยว่าในอวกาศเราเอาแม่เหล็กจะดูดเอาอะตอมธาตุเหล็กในอวกาศได้หรือเปล่าครับผมสงสัยจังครับ
Hello NASA space king 🇺🇸🇺🇸🇺🇸🇺🇸👑👑👑👑
Questions-
Do earths flux tubes convey within the planet?
If so when using the Australian arrays split fields have you timed the conveyor speed by taking sequenced / timed snapshots of the earths flux tubes?
&, Do the flux tubes 'accelerate' when they are bombarded by solar radiation?
Have you attempted live recordings of the earths flux tubes from satellites yet?
Or is this new magnetic soup mesh blocking it (hence the discovery)?
Noise sorry-
an MMS is yet another thing NASA has sent that I never will.
yea thanks but I figured that out in 2012
What about the magnetosphere of the sun?
👍 nice. Earth shield
Jupiter looks like plasma vortexes
Wow, if you treat Earth as an eye, it looks alot like how our eyes perceive light 😮
What ? Who ? When ? Wtf
No. The worlds ground positioning system has been established from the late 1800s.
what if you could somehow harness and ride this energy in a space craft. mabye there are space portals
ماذا لو صعقنا البحار بالكهرباء لازالة الغلاف المغناطيسي ?
Could this be causing trumpet noises?
and the trumpets they go, dat dat dadda dadda dat dat
could it be a way to connect the quantum theory with relativity theory?
no
There are two very different things.
Quantum is subatomic scale, relativity is cosmic scale.
They don't kiss.
Please make videoes in hindi
Gravity? I thought it was space-time bending due to earth mass.
Wow
I see a clue of how all the water got here. Dusty snowball comets are out. Turn back the clock and take what we know. Hydrogen coming from the sun, oxygen ejected into space from impacts and now the energy needed to fuse it into water. Now how would it condense and fall back to Earth? Has anyone checked orbital space for H2O molecules? Maybe I'm just crazy.
Now humans are on a path to new frontiers. Congratulations.
I will teach starx harness power
Maybe this is why earth will stop spinning.
finding a force means using a force
Spheretext
So many people with so much to lose.
It would seem to me that positing 'energy transfer' via (imaginary) magnetic field lines through a turbulent ionized plasma is a very convoluted way of saying you have detected electrical current flow in space. Just sayin'.
we must travel through the aether
Oh great... the electric universe guys are going to go crazy with this, again, pointing out how they knew it all along and how in the dark mainstream is/has been. Until know, the tightness and level of this energy has been completely unseen -- "dark" almost. We would need to add this to our models and rework them, but first we need to know what it looks like in more than just one point in outer space.
If I found a portal I would’ve went In it without hesitation any place could be better than here
Same haha
What's next? "Space miles"? 🤦♂️
Crazy °.°
bermuda triangle is a portal
but without gravity out univers
The new science resembles the ancient Alchemy.
The new technologies and knowledge, sure, but the process of science, the "Scientific Method", remains relatively unchanged from the time of Aristotle and certainly since being codified and promoted by Roger Bacon in the 13th century.
you're pretty old!
Modern people feel amazed by the ancient people's creation of the Pyramids in Egypt; but they refused to be amazed by the creator of the universe.
prove it exists and i will be amazed
It turns out that electromagnetic activity is so dominant it will force a new universal physics model. Magnetic reconnection was an effort to stop this from happening by patching the old model.
Exactly.
Astral Traveler and ... you think reconnection works well how? What do you think a field line is? The spin itself is a variable that is irrelevant to the electric and magnetic state even when you run a magnetic field over an electric current, the conductor temp will increase as it forces greater resistance by inducing faster atomic spin rates, however
how is any of this connected to reconnection?
Astral Traveler Gatcha, just for something to consider, what if they represent layered charge density and are similar to how a group of people trying to pass through a larger group would form orderly lines in the same direction to reduce collisions. Electrons have already been observed to have layers, shells or envelopes. What if you are looking a huge electron? I mean you have to shoot electricity through it to create it. Reconnection would be as silly as waves that form on the ocean or sandy dessert at 90 degrees to the wind being said to "reconnect". Just something to consider.
NASA !@! NASA!!!!!!! We CAN TRANSFER DATA THROUGH PLASMA.
NOT BLOOD PLASMA. I AM TALKING ABOUT LIGHT PLASMA. WORK THROUGH IT
sweet
Turbulent Plasma = Turbulent Juice???
finaly :)
Chaos theory at work.
Quantum mechanics in a nutshell
woahhh
i love it when people don't have a clue about what they "believe" and then go rampanging on "no, the theory i believe more is the one that is correct" "no no no, it is impossible for that theory to exist because mine is better" you all look like the superstitious folk that constantly battle over something that they do not see or prove or even know about! we know so little about the universe and yet you all act like you have been everywhere on it
If this is true, can we at least see the real thing rather than animations?
ytmoog then this proves the video is fake
plezx29 ???
HEH HEH......
Sheath
Is it possible that all matter when energized by an external quantum force is jostled along through 'time' by a rapid oscillation between a true fourth dimensional plasma state and then de-energized back to 'ordinary matter'? Is it accepted as fact that what is viewed as changes in the 'state' of matter are actually a dimensional transition from solid (1d), liquid (2d; covering a flat plane), and gas (3d; filling a volume)? In this case, can a true plasma ever actually be observed, or are we seeing a rapid phase oscillation when looking at something like a star?
For that matter, I wonder if there are perhaps infinite dimensional states that we are for whatever reason of happenstance incapable of 'seeing' because we are bound to this particular energy region.
Why are all these channels calling energy discharges particles? So dumb...
because particles can carry energy
Aum mane padme hum l
Mankind studied & learned this much about how fragile & opportunistic our existence on Earth is, but aren't doing anything about Humankind's Fragmented Nature which will inevitably spell the end of Mankind on Earth, even before these studied changes will decimate all living things on this planet of ours, which, we are still destroying all for MONEY & POWER. Doesn't this make us, Primitive instead?
it would be nice if this video used kilometers instead of miles
Do you spend the rest of your day trolling South Asian sites over their use of crore and lakh?
Actually, NASA had adopting international metric system since 2007. Not realy suprising since only USA and 2 other country still using the american metrics. Not very important for everyday stuff but when you have a worldwide community of scientists,it's important to have the same system metrics who can greatly reduce stupid errors (mars orbiter for exemple)
Why? Most English speaking countries use miles and not kilometers
+Djinn NASA was using SI as a whole in 1962 or so. US Customary (USC) had been systematized to metric in the 1870s or so. The only reason that USC was used so late in industry was because of slow adoption by aerospace companies not needing to switch units since units don't define "scienceness". They only facilitate intercommunication between parties. After the Mars Polar Lander catastrophe, the US companies were constrained to align their design and operational units with SI.
+plezx29
Actually only the US, Myanmar and Liberia still use miles.
+tigeruby
NASA unfortunately relies on the US Congress for funding, which is mostly made up of lawyers who aren't smart enough to do the conversion and would feel offended if they thought NASA was talking down to them. All their internal documentation uses metric units.
